Definitions

  • the present invention relates to a windscreen wiper device of the flat blade type comprising an elastic, elongated carrier element, as well as an extruded elongated wiper blade of a flexible material, said wiper blade comprising a wiping element which can be placed in abutment with a windscreen to be wiped, which wiper blade includes a central longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein said oscillating arm can be pivotally connected to said connecting device about a pivot axis near one end thereof .
  • Such a windscreen wiper device is generally known.
  • This prior art windscreen wiper device is designed as a so-called “flat blade” or “yokeless blade”, wherein no use is made of several yokes pivotally connected to each other, but wherein the wiper blade is biassed by the carrier element, as a result of which it exhibits a specific curvature.
  • the object of the invention is to provide an improved windscreen wiper device.
  • a windscreen wiper device of the type referred to in the introduction is characterized according to the invention in that said groove extends in downward direction beneath the longitudinal strip for forming a longitudinal hollow channel defined by said longitudinal strip and a bottom of said groove, wherein a height of said hollow channel at the location of a middle longitudinal plane of said wiper blade perpendicular to the windscreen to be wiped is defined by: wherein W is a width of the longitudinal strip, and
  • H is a height of the hollow channel at the location of a middle longitudinal plane of said wiper blade
  • the present windscreen wiper device can be used for large varieties of windscreens to be wiped mutually differing in their curvatures.
  • the hollow channel or "gap" between the longitudinal strip and the bottom of the groove generates a flexibility of said bottom and thus a variation of the position of the wiping element in a
  • the height of said "gap” may vary, dependent on the pressure exerted by the oscillating arm on the wiper blade.
  • the wiper blade being made of a flexible material, particularly rubber, may deform in accordance with said pressure, so that the "gap" between the longitudinal strip and the bottom of the groove may decrease in case of an increase of said pressure or may increase in case of a decrease of said pressure.
  • the wiper properties are improved, as hazing is avoided at a location of a centre of the wiper blade at high pressures exerted by the oscillating arm.
  • said groove extends in upward direction above the longitudinal strip for forming a
  • longitudinal hollow channel defined by said longitudinal strip and an upper surface of said groove.
  • said wiper blade is provided with a spoiler at a side thereof facing away from a windscreen to be wiped.
  • figure 1 is a perspective, schematic view of a
  • FIG. 1 shows a preferred variant of a windscreen wiper device 1 of the flat blade type according to the invention.
  • Said windscreen wiper device 1 is built up of an elastomeric wiper blade 2 comprising a central or middle longitudinal groove 3, wherein a central or middle longitudinal strip 4 made of spring band steel is fitted in said longitudinal groove 3 (see figures 2 through 5) .
  • Said strip 4 forms a flexible carrier element for the rubber wiper blade 2, as it were, which is thus biassed in a curved position (the curvature in operative position being that of a windscreen to be wiped) .
  • An end of said strip 4 and/or an end of said wiperblade 2 may be connected on either side of the
  • the connecting pieces 5 are separate constructional elements, which may be form- locked, as well as force-locked to both ends of said strip 4/said wiper blade 2.

  • the windscreen wiper device 1 is furthermore built up of a connecting device 6 for connecting an oscillating wiper arm 7 thereto.
  • the oscillating wiper arm 7 can be pivotally connected to the connecting device 6 about a pivot axis near one end.
  • the preferred embodiment of figure 1 according to the invention comprises a spoiler or "air deflector" 8 which is made in one piece with the rubber wiper blade 2 and which extends along the entire length thereof.
  • the connecting device 6 with the wiper blade 2 is mounted onto the oscillating arm 7 as follows.
  • a joint part 9 being already clipped onto the connecting device 6 is pivoted relative to the connecting device 6, so that said joint part 9 can be easily slided on a free end of the oscillating arm 7.
  • a resilient tongue 10 of said joint part 9 is initially pushed in against a spring force and then allowed to spring back into a hole 11 of said oscillating arm 7, thus snapping, that is clipping the resilient tongue 10 into the hole 11.
  • This is a so-called bayonet-connection.
  • the oscillating arm 7 together with the joint part 9 may then be pivoted back in a position parallel to the wiper blade 2 in order to be ready for use.
  • the connecting device 6 and the joint part 9 together with the wiper blade 2 may be released from the oscillating arm 7. Dismounting the connecting device 6 with the wiper blade 2 from the oscillating arm 7 is thus realized by sliding the connecting device 6 and the joint part 9 together with the wiper blade 2 in a direction away from the oscillating arm 7.

  • said oscillating arm 7 is connected to a mounting head fixed for rotation to a shaft driven by a small motor. In use, the shaft rotates alternately in a clockwise and in a counter-clockwise sense carrying the mounting head into rotation also, which in turn draws said oscillating arm 7 into rotation and by means of said
